Actually... Dan Dihn explained this while streaming a week or 2 ago. Haha
Basically you farm and push your lane. Don't trade with him... Then b and buy. This puts you ahead of him if he doesn't b. Repeat this till 6. Once you have your ult you can trade. Ult and go HAM on vlad and farm. Your gonna wanna keep farming and b'ing to stay ahead. This won't necessarily win the lane but it will keep you farmed and he will lose vs if you keep pushing to his tower and b'ing
